Negative Effect
A main human impact that effects the tropical rainforest is logging. Typical logging operations are damaging to the rainforest ecosystem. Problems stem from the nature of limited-term timber concessions, which encourage short-term resource depletion, and poor forest planning and management. Corruption is rife in many tropical timber-producing countries, The structure of the rainforest itselfmeans that it can simply be more profitable to clear- cut forest. Even without clear-cutting, the construction of logging roads to reach forest resources is destructive in the its own right and encourages settlement of previously inaccessible forst lands by speculators, land developers, and poor farmers. Studies by the Environmental Defense Fund show that areas that have been selectively logged are eight times more likely to be settled and cleared by shifting cultivators than untouched rainforests because of the access granted by logging roads.Without the trees with roots that keep in the nutrients of the soil in the rainfosests the soil nutuients are washed away when it rains.
Negative Effect
The element phosphorus is found naturally in the air, soil, rocks, and some organic materials.Phosphorus exists in rocks and soil minerals as the inorganic ion, phosphate.Phosphate ions are mainly found in the phosphorus cycle.The cutting down of tropical rainforest has led to a disruption in the phosphorus cycle in the entire world.The tropical rainforest is an ecosystem that is supported by almost 100% nutrient recycling.There is little or no reserve contained in the soil of the ecosystems, and nutrients are almost entirely stored in organisms.If there is too little phosphorus in the soil, a number of the plants will not be able to receive the nutrients they require, and die.If the soil used for agriculture contains too little phosphorus, the crops will do poorly, and will also remove nutrients.Since the majority of life in a rainforest depends on the large trees, once one of the large trees die, all of the life contained dies along with it.When there is not enough plant life to hold the soil in place, erosion occurs, which causes nutrients to wash away, which in turn causes more plants to die, and so on in a vicious cycle.
Positive Effect
An increase in tourism has increased economic support, allowing more revenue to go into the protection of the habitat. Tourism can contribute directly to the conservation of sensitive areas and habitat. Revenue from park-entrance fees and similar sources can be utilised specifically to pay for the protection and management of environmentally sensitive areas. Revenue from taxation and tourism provides an additional incentive for governments to contribute revenue to the protection of the forest.
Positive Effects
Tourism also has the potential to increase public appreciation of the environment and to spread awareness of environmental problems when it brings people into closer contact with the environment. Such increased awareness can induce more environmentally conscious behavior. Tourism has had a positive effect on wildlife preservation and protection efforts, notably in Africa but also in South America, Asia, Australia, and the South Pacific.
